By Ruby Prosser Scully. Deep-sea fish have evolved transparent teeth which, along with their black bodies, make them invisible to prey. While dragonfish are only the size of a pencil, they are fearsome predators at the top of the food chain. Their thin, eel-like bodies support a huge black mouth filled with razor-sharp teeth, that can widen to swallow prey half their size.

The deep sea dragonfish , sometimes known as the scaleless dragonfish, is a ferocious predator that inhabits the deep oceans of the world. Known scientifically as Grammatostomias flagellibarba, it has extremely large teeth compared to its body size. In spite of its gruesome appearance, its is a small fish, measuring only about 6 inches about 15 centimeters in length. There are several different species of dragonfish. All are very similar in appearance. The deep sea dragonfish is one of the many species of deep sea fish that can produce its own light through a chemical process known as bioluminescence. The light is produced by a special organ known as a photophore. It is believed that the fish can use these flashing lights in the dark waters to attract prey and even to signal potential mates.

All rights reserved. The Asian arowana, also known as the dragon fish, is believed by the Chinese to bring good luck and prosperity due to its red color and coin-like scales. One woman risked terrorists, headhunters, and the 'fish mafia' to see an Asian arowana in the wild. Traveling to 15 countries, she braved headhunters and civil war to follow the trail of a fish that is often transported under armed guard. When National Geographic caught up with her by phone at her home in New York, she explained how a well-meaning conservation effort to protect the arowana paradoxically increased its attractiveness to collectors; how her search for the arowana took over her life; and why putting a fish in a tank is part of our innate desire to connect with other species.
Unassuming dragonfish lurk in the twilight zone, more than 1, feet under the surface of the ocean. In a paper published Wednesday in the journal Matter, scientists demonstrated another layer of complexity to the dragonfish : the thin, jagged teeth of the species Aristostomias scintillans are made of nanoscale-size crystal particles.

And for material scientists, understanding the details of dragonfish teeth could help lead to new synthetic materials that are both strong and transparent, said Emanuela Del Gado, a material physicist at Georgetown University, in Washington D. Neither she nor Dr. Webb were involved in the study. Marc A. Meyers, the lead author of the new paper and a materials scientist at the University of California, San Diego, has long studied animals for inspiration to develop novel materials.
